Autonomous driving systems require a comprehensive understanding and accurate prediction of the surrounding environment to facilitate informed decision-making in complex scenarios. Recent advances in learning-based systems have highlighted the importance of integrating prediction and planning. However, this integration poses significant alignment challenges through consistency between prediction patterns, to interaction between future prediction and planning. To address these challenges, we introduce a Hybrid-Prediction integrated Planning (HPP) framework, which operates through three novel modules collaboratively. First, we introduce marginal-conditioned occupancy prediction to align joint occupancy with agent-specific motion forecasting. Our proposed MS-OccFormer module achieves spatial-temporal alignment with motion predictions across multiple granularities. Second, we propose a game-theoretic motion predictor, GTFormer, to model the interactive dynamics among agents based on their joint predictive awareness. Third, hybrid prediction patterns are concurrently integrated into the Ego Planner and optimized by prediction guidance. The HPP framework establishes state-of-the-art performance on the nuScenes dataset, demonstrating superior accuracy and safety in end-to-end configurations. Moreover, HPP's interactive open-loop and closed-loop planning performance are demonstrated on the Waymo Open Motion Dataset (WOMD) and CARLA benchmark, outperforming existing integrated pipelines by achieving enhanced consistency between prediction and planning.
自动驾驶系统需要对周围环境有全面的理解和准确的预测,以便在复杂场景中做出明智的决策。基于学习的系统的最新进展凸显了整合预测与规划的重要性。然而,这种整合通过预测模式之间的一致性,到未来预测与规划之间的交互,带来了重大的对齐挑战。为应对这些挑战,我们引入了一种混合预测集成规划(HPP)框架,该框架通过三个新颖的模块协同运作。首先,我们引入边际条件占用预测,以使联合占用与特定智能体的运动预测对齐。我们提出的MS-OccFormer模块在多个粒度上实现了与运动预测的时空对齐。其次,我们提出了一种博弈论运动预测器GTFormer,基于智能体的联合预测感知来对它们之间的交互动态进行建模。第三,混合预测模式同时被集成到自我规划器中,并通过预测引导进行优化。HPP框架在nuScenes数据集上建立了当前最优的性能,在端到端配置中展示了卓越的准确性和安全性。此外,HPP在Waymo开放运动数据集(WOMD)和CARLA基准上展示了交互式开环和闭环规划性能,通过在预测与规划之间实现更高的一致性,优于现有的集成管道。
